ʻO ka hao hoʻoheheʻe he hao-carbon hoʻoheheʻe ʻia me nā mea ʻē aʻe i hana ʻia e ka hoʻoheheʻe ʻana i ka hao puaʻa, ʻōpala, a me nā mea hoʻohui ʻē aʻe. No ka hoʻokaʻawale ʻana mai ke kila a me ke kila hoʻoheheʻe ʻia, ua wehewehe ʻia ka hao hoʻoheheʻe ʻia e like me ka mea hoʻoheheʻe ʻia me kahi mea kalapona (min 2.03%) e hōʻoiaʻiʻo ai i ka paʻa ʻana o ka pae hope me kahi hoʻololi eutectic.
Ma muli o nā kikoʻī kemika, hiki ke hoʻohui ʻole ʻia nā hao hao. ʻOi aku ka laulā o ka nui o nā hao i hoʻohui ʻia, a ʻoi aku ka nui o nā mea maʻamau, e like me ke silikoni a me ka manganese, a i ʻole nā mea hoʻohui kūikawā, e like me nickel, chromium, aluminika, molybdenum, tungsten, copper, vanadium, titanium, plus nā mea ʻē aʻe. Ma ka ʻōlelo maʻamau, hiki ke hoʻokaʻawale ʻia ka hao i loko o ka hao hina, hao ducitle (hao nodular), hao keʻokeʻo, hao graphite paʻa a me ka hao malleable.

ʻO ka hao hoʻoheheʻe ʻia, ʻo ia hoʻi ka mea i kapa ʻia ʻo nodular cast iron, spheriodal graphite cast iron a i ʻole SG hao wale no ka pōkole, e hōʻike ana i kahi hui o ka hao. Loaʻa ka hao nodular i ka graphite nodular ma o ka spheroidization a me ka mālama inoculation, kahi e hoʻomaikaʻi maikaʻi ai i nā waiwai mechanical o ka hao, ʻoi aku ka paʻakikī a me ka paʻakikī, i loaʻa ai ka ikaika kiʻekiʻe ma mua o ke kila kalapona.
ʻOi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka hao ma mua o ke kila kalapona, ʻoiai ʻoi aku ka maikaʻi o ka weldability o ka hoʻoheheʻe ʻana. A i kekahi manawa, hiki i ka ductile iorn castings ke loaʻa i kekahi mau hana o ka pale ʻana i ka lole a me ka ʻōpala. No laila hiki ke hoʻohana ʻia ka hoʻolei hao ductile no kekahi mau hale pahū a i ʻole nā pūnaewele wai. Eia nō naʻe, pono mākou e mālama i ka pale ʻana iā lākou mai ka ʻaʻahu a me ka ʻōpala.
ʻAʻole ʻo Ductile iron he mea hoʻokahi akā he ʻāpana ia o ka pūʻulu o nā mea hiki ke hana ʻia e loaʻa i kahi ākea ākea ma o ka mālama ʻana i ka microstructure. ʻO ka hiʻohiʻona maʻamau o kēia pūʻulu mea ʻo ke ʻano o ka graphite.

No laila, ma ka ʻōlelo maʻamau, inā hiki i ka hao ductile ke hoʻokō i kāu mau koi, ʻo ka hao ductile paha kāu koho mua, ma kahi o ke kila kalapona no kāu hoʻolei ʻana.
